DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NMTP2022/7/"
 >Interior eigenvalue problem for localisable quantum lattice models in con
 densed matter</a>\nby Fabien Alet (CNRS) as part of Numerical Methods in T
 heoretical Physics\n\n\nAbstract\nI will provide an overview of numerical 
 techniques that have been proposed to obtain eigenstates deep in the middl
 e of the spectrum of many-body quantum systems. This problem is particular
 ly relevant for systems which do not follow the eigenstate thermalization 
 hypothesis.  I will discuss spectral transforms methods  -- trying to revi
 ew different strategies and works --\, and focus in particular ont the shi
 ft-invert technique. Examples of applications in the field of many-body lo
 calization will also be presented. In conclusion\, perspectives will be gi
 ven on how to perhaps improve these methods and applications to other fiel
 ds.\n
